APPARATUS FOR MAKING AND RAISING SALT-BRINE FROM DEEP SALT-VEINS.

".uPECIPICATION forming part of Letters Patent No. 327,308, dated September 29, 1885. Application filed March 3, 1885. (No model.)

To (ZZZ whom it may concern:

Be it known that I, JOHN PETERS, of Haverstraw, in the county of Rockland and State of New York, have invented a new and Improved Apparatus for Making and Raising Salt-Brine from Deep Salt-Veins, of which the following is a full, clear, and exact description. i

In obtaining the salt from deep strata of salt-rock,where it is impracticable to mine by shafts and drifts, it has been the practice to sink wells down into the salt deposit, and to supply them with outside and inside pumping machinery arranged for pumping fresh water into the well, and then pumping it out again after it shall have become saturated with salt.

By my new apparatus I employ only outside pumping machinery arranged to force the fresh water into the we]! permit it to dis solve salt by contact with the underground deposit and become brine, and then to expel the same from the Well by pressure, thus, doing away with inside pumping machinery.

The machineryI employ consists of a forcepump combined with suitable inflow and outflow pipes arranged in the well, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming part of this specification, which represents a sectional elevation of a salt-well having my invention applied thereto.

A represents a deep well, which extends down into the salt stratum illustrated at B. In the well A is placed the inflow pipe or casing 0, which reaches down below the freshwater veins in the earth,where the pipe or easing O is suitably packed, as shown at d, for excluding drainage from the well below and for confining the water below the packing, so that the brine may be expelled from the well through the outflow-pipe E by pressure upon the brine in the well.

D is a force-pump, by which fresh water may be pumped from a spring or other supply into the well through the inflowpipe C and by which pressure may be applied to th water in the well for forcing it out of the we] through the outflow-pipe E. This pressur upon the water not only serves to elevate th brine from the well without the aid of sepa rate pumping machinery, but it also force: the water in the well into the small crevice: of the salt deposit, and causes the water ti dissolve the salt and become brine much mom rapidly than where no pressure is used.

The outflow-pipe E might be arranged out side of the inflow pipe or casing C; but I pre fer to arrange it inside of said pipe or easing G, as shown in the drawings; and it is obvious that where there is a natural or artificial head or pressure of water near the mouth of the well the force-pump might be dispensed with, using the natural pressure of the water in its stead to supply the well with water and force the brine out.

The brine, after being forced out of the well, is concentrated in the usual manner for obtaining the salt.

This application is a division of my application filed June 12, 1883.

I am aware that it is not broadly new to raise oil or other liquids from deep wells by hydraulic or pneumatic pressure, and I do not broadly claim such devices.

WVhat I claim is- 1. The combination of the force-pump with the inflow and outflow pipes arranged within the well and with reference to a subterraneous deposit of salt, substantially as described.

2. A tube orcasing, O,placed in the well and packed at d, in combination with an outflowpipe, E, through which brine may be forced out of the well, substantially as described.

JOHN PETERS.
